Paris-Geneva-Manama, 29 August 2018 – For the second time since 2013, the United Nations (UN) Working Group on Arbitrary Detention (WGAD) has issued an Opinion regarding the legality of the detention of Mr. Nabeel Rajab under international human rights law. In its second opinion, the WGAD held that the detention was not only arbitrary but also discriminatory. The 127 signatory human rights groups welcome this landmark opinion, made public on 13 August 2018, recognising the role played by human rights defenders in society and the need to protect them. We call upon the Bahraini Government to immediately release Nabeel Rajab in accordance with this latest request.
